virt_to_pfn has been defined in asm/memory.h by the commit e26a9e0 "ARM: Better virt_to_page() handling" This will result of a compilation warning when CONFIG_XEN is enabled. arch/arm/include/asm/xen/page.h:80:0: warning: "virt_to_pfn" redefined [enabled by default] #define virt_to_pfn(v) (PFN_DOWN(__pa(v))) ^ In file included from arch/arm/include/asm/page.h:163:0, from arch/arm/include/asm/xen/page.h:4, from include/xen/page.h:4, from arch/arm/xen/grant-table.c:33: The definition in memory.h is nearly the same (it directly expand PFN_DOWN), so we can safely drop virt_to_pfn in xen include.
